BROWN, 0)? CLEVELAND, OHIO.

RESIDENT SHOE-HEEL.

Application filed April 8, 1915.

To all whom it may concern:

Be it known that 1. JOHN H. BROWN, a citizen of the United States, residing at Marseilles. in the county of La Salle and State of Illinois, have invented'certain new and useful Improvements in Resilient Shoe- Heels, of which the following is a specification.

This invention relates to resilient shoe heels and has as its object to provide a heel of this class so formed that it will not be liable to slip upon snowy or icy surfaces but will, on the other hand, more or less firmly adhere to such surfaces. The results aimed at are attained by the provision in the face of the heel of a recess of such shape as to prevent slipping either in a forward or rearward direction or laterally in either direction, and it is another aim of the invention to so form this recess that snow or mud will not be liable to accumulate therein but will, on the other hand, be automatically discharged therefrom in the act of walking.

In the accompanying lrawings, Figure l is a perspective view; of the heel emlx'idying the present invention. Fig. 2 is a bottom plan view thereof. Fig. 3 is a vertical l0ngritudinal sectional view on the line 33 of Fig. 2. Fig. 4 is a perspective view looking at the upper side of the heel.

(orresponding atid like parts are referred to in the following description and indicated in all the. views of the accompanying drawings by the same reference characters.

In the drawings the heel is indicated in general by the numeral 1 and is of rubber or any other suitable elastic or resilient composition, and the heel is provided with a number of openings 2 through which securing" nails or tacks may be driven for the purpose of attaching the heel to an ordinary leather shoe heel.

In order to prevent slipping of the heel 1 either in a forward or rearward direction or either lateral direction, the heel is formed in its under face with a recess which is substantially T-shapcd. That portion of the recess which corresponds to the stem of the T is indicated by the numeral 2 and that portion which corresponds to the head of the T is indicated at 3. The first mentioned portion forms a juncture with the portion 3 at a point midway between the ends of the latter and is located at the front to rear median line of the heel, the portion 3 ex- Specification of Letters Patent.

tending transversely of the heel and at right angles to the portion 2 of the recess. Both portions 2 and 3 of the recess are preferably of the same depth and both are relatively deep and by reference to the drawings it will be observed that both portions of the recess are restricted inwardly. In other words, the bottom walls of the portions 2 and 3 are of less length and width than the open sides of the said portions of the recess, and while the walls of the said portions are here shown as relatively inclined and occupying planes, it will be understood that they -niay be more or less rounded or convex if desired. By reason of the peculiar relative inclination of the walls of the portions 2 and .l of the recess and the fact that the said portions are inwardly restricted, any mud or snow forced into the recess when the heel is placed in the act of walking will be automatically dislodged when the heel is lifted, or, in other words, will fall from the recess. It will further be apparent that inasmuch as the two portions of the recess are in con'ununicatiou with each other and the heel is of resilient or compressible material, suction will be created when the heel is placed upon a smooth or slippery surface which will prevent slipping of the heel.

By reference to Figs. 1 and 2 of the drawings it will be observed that the openings 2 are arranged in a series surrounding the recess and that two of these openings are located at opposite ends of the portion 3 of the recess: that one of the openings is located at the forward end of the portion 2 of the recess; and that another of the openings is located rearwardly beyond the middle of the portion 3 of the recess. By reason of this relative arrangement of the openings for the securing elements and the recess, the heel may be securely fastened to the ordinary leather heel at points surrounding, the recess and consequently the heel will not be materially weakened even though the recess be formed relatively deep. I

the point of intersection of the branches of the recess than at any other point and air will be more c :pletely expelled from this recess, thereby increasing the adhesion of the heel to the surface upon which it is disposed.

Having thus described the invention, what is claimed as new is: n

l. A cushion tread member for shoes having a suction recess in its tread surface and provided upon its attaching face with a protuberance located opposite the said recess, the said protuberance constituting a means for depressing inwardly the wall of the access to the more effectually expel the air from the recess when downward pres sure; .5 exerted against the said protuberance by the flat under surface of a heel lift to whi h the said member is secured.

2. A cushion tread member for shoes having recess in its tread surface and providxd With a protuberance upon its attach- 'ingfi. face located opposite the said recess, the member throughout the area of the protuband the said promeans for detrance being imperforate tuberairce constituting a pressing inwardly the wall of the recess to the more effectually expel the air from the recess when downward pressure is exerted against the said protuberance by the flat under surface of a heel lift to which the said member is secured.

3. A cushion tread member for shoes having a recess in its tread surface andprovided with a protuberance upon its attaching face located opposite the said recess, the said attaching face except for'the protuberance being plane and the said protuberance constituting a means for depressing inwardly the wall of the recess to the more effectually expel the air from the recess when downward pressure isexerted against the said protuberance by the flat under su rface of a heel lift to which the said memher is secured.

In testimony whereof I affix my signature in presence of two witnesses.
